' SPECIFICATION forming part of Letters Patent No. 315,522, dated April 14, 1885.

l Application filed October 7, 1884. (No model.)

.T0 @ZZ whom, t may concern/.-

Be it known that I, CHARLES B. LovELEss, a citizen of the United States, residing at Worthington, in the county of Nobles and State of Minnesota, have invented certain new and useful Improvements in Ventilators; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a side elevation `of my invention, showing it in use as an attachment to a chimney; and Fig. 2, a sectional elevation of the invention, with the addition of the induction-pipe to adapt it for use as a ventilator for vaults, closets, and other structures.

The present invention has for its object to provide asimple and effective ventilator that can be used on chimneys to produce a partial vacuum, and consequently a draft or suction to carry upward the ascending smoke and cinders to the lpoint of discharge, and also employed as a means for Ventilating vaults and other similar structures by the withdrawal of the foul or vitiated air and the introduction of fresh or pure air. These objects I attain by the construction, substantially as shown in the drawings and hereinafter described and claimed.

In the accompanying drawings, A represents the discharge-pipe, through which the smoke and einders or foul air pass and escape, said pipe at its upper end being provided with a suitable cap, a, to deliect the smoke and other volatile products of combus-v tion as they escape from the pipe. A pipe, B, which I shall term a suction-pipa7 passes through the side of the pipe A, and extends upward some distance, to near the top thereof, to render the ventilator more effective in producing the suction or required draft. VThe outer portion of the pipe B, or that portion located upon the outside of pipe A, is of sufficient length to extend some distance above the same, so as to create a suction of greater force and power, this especialv feature being cal operation of the device. To the upper end of the pipe B is attached a revolving cowl, C,

of any of the usual forms, and conducting the wind down the pipe by the mouth of the cowl being at all times brought to the properv posi- Vtion or in the directionu the wind is blowing.

At the bend in the pipe B a drip-hole,b, is formed to admit the escape of any collected moisture or rain entering the pipe, thereby not affecting the passage of the air through the pipe and leaving it all times unobstructed.

When the ventilator is employed in vaults,

essential in insuring the successful and practii closets, and other similar structures to expel foul air and introduce vital` air, I provide the suction-pipe B, at the elbow or bend thereof, with an induction tube, D,'communicating with said' pipe and extending down any suitable distance into the vault or other structure. By the employment of the tube D a sufficient amount of vital air passes down said tube into the vault by'force at the same time the suction-pipeA B and into the pipe A to slick or draw the foul or vitiated air from the vault, the tube D furnishing sufficient air to keep up a strong circulation in the vault.

The introduction of a small portion of air l structures it may be of sufficient length to extend down some distance therein, and when the device is employed as in the ventilation with, in which case the rain or moisture would escape through the tube D into the vault.

Having now fully described my invention,

vof vaults the drip-hole a may be dispensed the body or larger amount of air passes through what I claim as new, and desire to secure by l In testimony that I claim the above I have Letters Patent, ishereunto subscribed my name in the presence io In a ventilator, the combination, with a disof two witnesses.

charge-pipe, ofa suetionepipe extending above it and provided with a revolving cowl, and CHARLES B LOVELESS' at or near its lower end with an inductiontuloe of less diameter than the suction-pipe, substantially as and for the purpose specified.
